Site Development

With our mid-sized excavation division, Onyx can meet the needs of both private and municipal clients. We have experience with jobs large and small, from excavating for small foundations to complex municipal infrastructure work. We understand the rigorous standards needed to meet not only state and local regulations but also the meticulous expectations of a homeowner. Our 30 plus years of experience working in all types of subsurface soil conditions, allows us to manage every project efficiently and effectively, so you can rely on us to complete your job on time and on budget.

Most every project begins with the establishment of a well thought out plan as well as a thorough understanding of the needs and constraints your project may have. We bring a unique perspective to your project. Years of working with hundreds of professionals has exposed our team to many project challenges that enables us to anticipate and tackle unforeseen site conditions. Drawing on our team’s years of experience we welcome the opportunity to assist in the initial stages of planning, value engineering and/or peer reviewing your project to ensure you’re getting the most for your budget.

On every project we are engaged in, we strive to maintain the overall health and integrity of the site and its surroundings. We’re sensitive to the environment in every decision we make, reusing and recycling materials as much as possible, and have extensive experience working on LEED certified & accredited projects.

We have a large fleet of heavy equipment, trucks and access to our own construction materials, so we guarantee you a competitive rate, without cutting corners or sacrificing quality. Onyx is MassDOT Certified to complete single projects up to 5 million dollars in value, we are fully bonded and insured, and our employees are OSHA- and/or MSHA-certified, with many trained in first aid – meaning that you can rest assured that your site will be managed to the highest standard.

My husband and I have worked with Onyx on commercial projects, a major renovation at our church, and at our own home. Working with Julie and John and their crew was a delight from start to finish. They were creative, fun, responsive and respectful. The jobs were finished in a timely and professional manner and follow up was a priority. The results are beautiful and I would recommend Onyx to anyone.
